It has become a common feature of "modern" television making to have almost continuous background sounds behind all programmes, including news and current affairs and to liberally use sound effects even in documentaries and other factual output. The most prevalent explanation I have ever been given by those in the profession is that this practice is one of artistic licence and makes the programme more attractive for viewers. That by itself, I believe, is a highly contentious assertion and seems contradicted by the evidence whereby a substantial number of users express dissatisfaction with these practices. The artistic argument of course also implies it is subject to fashion, if not in the form of fads amongst the public (who do not seem to have much say in the matter and indeed whose opinions seem to be largely ignored by programme makers) of whimsical practice amongst those producing content.
